The front entrance to Tonic Restaurant with the sign "Quigley's Pharmacy."

Once a popular pharmacy and GW gathering place, the building at 619 21st Street, NW, has hung onto its importance as a GW hotspot. Although it retains Quigley?s Pharmacy's exterior facade, the building is now home to Tonic Restaurant, an American cuisine eatery that has revitalized the 21st Street address.
